Working with Particle Tracks

A track records the history of a parcel.

This history is the locus of parcel positions which can be visualized much like a streamline. Simcenter STAR-CCM+ allows other data to be recorded too, such as particle velocity and temperature, which can be used for subsequent visualization and analysis. Because there is the potential to generate a large amount of data, tracks can be recorded in a dedicated file under your control.

The particle track represents the track of one Lagrangian phase that is taken from a track file. A node of the particle track (named Continuum 1: Phase 1 tracks in the following screenshot) has its own properties.

This object is created automatically when you create a track file, and cannot be deleted directly. It is deleted only when you delete the track file that is associated with it. You can, however, rename this object.

To record a snapshot of the complete simulation at a given time, use a Simulation History File.

What Is the Particle Tracks Manager?

The Particle Tracks manager node contains all of the particle track nodes in the object tree.

The particle track manager can hold any number of particle tracks up to the memory limits of the computer.

Particle tracks get their data from track files. The Track Files node is the manager object for working with track files in the simulation tree. It is added to the tree once you select the Lagrangian Multiphase model. The track files manager can hold any number of track files up to the memory limits of the computer.
